Advanced System Design Interview, Volume II

Advanced System Design Interview, Volume II is the next step after the original best-selling Grokking the System Design Interview. It is built for engineers preparing for Senior, Staff, and L5/L6 interviews, where you are expected to design complex distributed systems and defend every trade-off under pressure. If Volume 1 taught you the vocabulary of system design, Volume II is where you build real fluency. It is ideal for mid-level and senior engineers who can already sketch a basic design and now want the depth to handle the hardest open-ended problems at top tech companies.

Volume 1 covers the foundations: the framework, the core building blocks, and classic design problems like a URL shortener or Instagram. Volume II goes deeper. It dissects the real distributed systems that modern infrastructure runs on and tackles harder, more ambiguous problems aimed at senior-level interviews. You do not strictly need Volume 1 first, but you should be comfortable with the basics before you start. Most learners take Volume 1 to build the vocabulary, then move to Volume II for the fluency that Staff and L5/L6 interviews demand.

Volume II is a deep dive into the systems behind real infrastructure. You study Dynamo, Cassandra, Kafka, BigTable, GFS, HDFS, and Chubby, learning how each one partitions data, survives node failures, and holds its consistency guarantees at scale. You then apply that knowledge to hard, open-ended design problems, including a distributed notification service, a flash-sale system, a payment platform, and a recommendation engine. The course also includes a dedicated System Design Patterns section covering consistent hashing, quorums, write-ahead logs, Merkle trees, CAP, PACELC, and more.

Yes. Senior and Staff interviews are not testing whether you can draw boxes on a whiteboard. They test whether you can architect for high availability, anticipate failure, and justify your decisions when the requirements get messy. Volume II is built specifically for that bar. With 142 lessons, 400 practice quizzes, and a guided mock interview on each major system, it gives you the depth and the repetition to walk in confident and lead the conversation rather than guess what the interviewer wants.

Advanced System Design Interview, Volume II was created by Arslan Ahmad and the team at Design Gurus, the same people behind the original Grokking the System Design Interview that has been taken by over 175,000 learners. Arslan is an ex-FAANG engineer and hiring manager who has built global-scale distributed systems at Microsoft and Meta and interviewed hundreds of candidates at both companies. That experience on both sides of the table shapes every lesson, so you learn not just how these systems work but what interviewers are actually looking for.

Volume II includes 142 lessons and roughly 36 hours of content, organized into deep-dive system breakdowns, hard design problems, and a System Design Patterns reference section. Nearly every module ends with a quiz, and the major systems include a walkthrough mock interview, for 400 quizzes in total. The format is self-paced, so you can move quickly through the topics you already know and slow down on the ones that matter most for your target role.
